I think this is your answer but i'm not sure. Hoped it helped!
The equation (4/5*2)4 will solve it because there are 60 minutes in 1 hour, and 2 times the thirty minutes gives us the hourly rate. The hourly rate (1.6 rooms) will then be multiplied to the 4 hours, to get 6.4 rooms painted in a matter of 4 hours. Answer= 6.4 rooms
2/3 is less than 7/8 because <span> 2/3= .66 and 7/8= .875</span>

Answer:
y=120-4x
Step-by-step explanation:
Here we are given the average speed for Day 1 and Day 2 and the time of ride . We asked to Find an expression to determine the total distance travelled in two days.
Day 1 :
Avg Speed = 8 mph
Let the time for travelling = x hrs
Hence Distace Travelled D1= Speed x Time
D1=8x
Day 2 :
Avg Speed = 12 mph
Total time of travelling for two days is given as 10 hours . Hence the time of travelling for day 2 is
= (10-x) hrs
Hence Distance travelled in Day 2 D2 = speed x time
D2 = 12(10-x)
D2=120-12x
Total Distance travelled = D1 + D2
= 8x+120-12x
=120-4x
If the total distance travelled is denoted by y
The expression will be
y=120-4x
